Verbs are the most important parts are sentences because they tell us everything we need to know about the sentence, including:

the subject of the sentence (person and number)

the voice of the sentence (active or passive)

the time of the sentence (tense)

When we first learned Latin verbs, we learned the personal endings of verbs. These are very important and they must be memorized. Once you know the personal endings, you can pretty much translate any verb you need.

We have active and passive personal endings for Latin verbs. Today, we'll focus on the active personal endings.

We will see these personal endings on most active verbs, including special verbs like sum. Therefore, it is very important that you memorize the endings in Latin and what they mean in English. If you know these endings and what they mean, then you can tell who/what the subject is.
